L’onagre est une plante originaire des États-Unis qui demande peu d’entretien, à l’exception d’un rabattage des tiges au printemps. De plus, elle supporte facilement tout type de sol. Vous pourrez donc facilement voir se développer de magnifiques massifs jaunes au printemps si vous veillez à tenir la plante hors de portée des ravageurs et maladies infectieuses !

Cette maladie peut se détecter par observation des parties aériennes. En effet, les feuilles pâlissent, jaunissent, puis sèchent et il y a un ralentissement du développement des nouvelles feuilles.

Les racines quant à elles se recouvrent d’une pourriture brune qui débute aux extrémités. On peut aussi observer dans certains cas une poussière blanchâtre sur le bulbe et la basse du pétiole. Le mieux que vous ayez à faire dans ce cas est de changer la plante de terre, en utilisant des substrats non asphyxiants (donc bien drainés).

Veillez à bien désinfecter les outils de jardin qui ont été en contact avec les plantes contaminées pour ne pas disséminer le champignon. Si les plants sont vraiment trop atteints, il faudra alors que vous les brûliez.

Cependant vous pouvez, en dernier recours, désinfecter le sol à la vapeur ou utiliser des fongicides comme le manèbe et le bénomyl.

Lutte contre les limaces

Bien que les limaces soient des ennemis redoutables de l’onagre, on peut facilement s’en débarrasser si l’on fait attention au milieu dans lequel évolue la plante.

Il faut savoir que les carabes et les hérissons sont de grands prédateurs des limaces, il est donc conseillé de ne pas les exterminer si vous voulez voir se développer vos massifs de sauge. De la même manière, le thym est un agent efficace pour repousser limaces et escargots, vous pouvez donc associer les deux plantes pour éviter des surcoûts inutiles en utilisant des pesticides.

Les limaces sont en outre attirées par les parties fanées ou pourries des plantes, veillez donc à les retirer le plus rapidement possible avant de favoriser l’apparition des ravageurs.
